Hi Internals.

Congratulations on the release of PHP 8.2.
I just recently upgraded production PHP from 7.4 to 8.1 :)

Now that my work is done, I was thinking about a proposal for a sunsetting
of existing functions for PHP 8.3 based on the features introduced in
ext-random, and I realized that there is no alternative to `lcg_value()`.

Essentially, this could be completely replaced by
Random\Randomizer::getFloat(), but there are easier `random_int()` and
`random_bytes()` functions for ints and strings.

The Randomizer may be overkill and complicated for PHP use cases where
random number reproducibility is not required in many cases.

So, why not add a `random_float(): float` function? This function, like the
others, uses CSPRNG and returns a value between 0.0 and 1.0. This behavior
is `Closed` `Closed`.

Opinions are welcome.

Regards,
Go Kudo
